    Frequently Asked Questions

    What are essential amino acids?

    Essential amino acids (EAAs) are amino acids that your body can’t produce enough of on its own, including leucine, isoleucine, valine, histidine, lysine, methionine, phenylalanine, threonine, and tryptophan. EAAs support muscle growth and recovery.

    What are micronized free-form amino acids?

    Micronized free-form amino acids are single amino acids that are already in a pre-digested form for faster absorption by the body.

    Why is nitric oxide important?

    Nitric oxide plays a key role in exercise endurance because it’s a vasodilator. A vasodilator is a substance that supports the dilation of blood vessels for increased blood flow.
